Child advocates urge backseat car alarms

A proposed new law that would require carmakers to build alarms for back seats is being pushed by child advocates who say it will prevent kids from dying in hot cars.

The law also would streamline the criminal process against caregivers who cause the deaths - cases that can be inconsistent but often heavier-handed against mothers.

The latest deaths came in Arizona on triple-digit degree days over the weekend, with two baby boys found forgotten in vehicles in separate incidents.

More than two dozen child and road safety groups are backing the U.S. Senate bill introduced last week aimed at preventing those kinds of deaths by requiring require cars to be equipped with technology that can alert drivers if a child is left in the back seat once the vehicle is turned off.
